Our invention relates to improvements in trucks for handling rolls ofnews print-paper. Rolls of print paper are quite heavy and I are subjectto considerable damage because of the several handlings necessary beforethey and it is the object of the present invention are mounted in apress for use.

These rolls must be delivered to newspaper plants; unloaded, andfrequently taken into the basements of.the printing oflices; then movedto a place of storage where they are up-ended, because they require lessspace when standing on end; then when needed, the rolls must be placedon trucks and moved to the press where they are removed from the handtrucks, placed upon spindles and hoisted in place on the ress.

These several andlings of each roll of paper, and particularly whenturning them from a horizontal to a vertical position, or vice versa,subjects the rim-edges of the rolls to bursting strains, and frequentlytears numerous wraps of paper on the rolls, which torn wraps are uselessand become a waste. Thousands of dollars are lost each year as theresult of the damage above referred to,

to facilitate the handling of these heavy rolls of paper and to reducethe damage to the same when handling.

With-this object in view, the invention is illustrated in theaccompanying drawings,

wherein,-

Fig. 1 shows the truck in side elevation and engaged with an uprightroll of paper.

Fig. 2 illustrates the truck and paper roll thereon in side elevationand the truck part- J ly lowered.

Fig. 3 shows the same but with the truck I and paper roll completelylowered.

Fig. 4 illustrates the truck in longitudinal sectional elevation and inthe partly lowered position.

Fig. 5 shows the truck in top or plan view. Fig. 6 illustrates thecylinder and piston in cross-section to show the ports therethrough, andv Fig. 7 illustrates the piston in rear elevation with the quick actingports therein indicated by broken lines.

, Referring to the drawings, the numerals 10- and the foremost cross-baris preferably provided with a toe-plate 12 for insertion be- .neath theroll.

Each side bar is of the angle-bar form and has a down-turned flange 13extending longitudinally along its inner side.

The cross-bars 11 are preferably concave across their upper sideswhereby to receive the rounded circumference ofthe rolls and hold thelatter from rolling laterally from the bed of the truck.

The truck proper consists of two front linkbars 14 and 15 and two rearlink-bars 16 and 17 ,the rear ends of the link-bars 14 and 15 lappingthe forward ends'of the link-bars 16 and 17 and both sets of bars beingpivotally mounted on the outer. ends of a cross-bar 18 which extendshorizontally through the downturned flanges 13-of the truck-bed.

The horizontal cross-bar 18 therefore forms a pivot on which the lappedends of the front and rear link-bars are mounted and also pivotallyconnects those la ped link-bar ends with the truck-bed. (lbtter-pins 19are passed through the ends of the cross-bar 18 and serve to retain thelapped link-bar-ends on the ends of the cross-bar.

The forward ends of the front link-bars 14 and 15 are pivotallysustained on a front shaft or axle 20, while the rear ends of the rearlinkbars 16 and 17 are pivotally mounted on the opposite ends of a rearshaft or axle 21.

Wheels 22 are provided on the opposite ends of the front axle whilesimilar wheels 23 are provided on opposite ends of the rear axle 21.

A cylinder 24, has arear head 25, with an enlarged lug 26 on the outerside thereof and this lug has a horizontal passage therethrough so thatthe rear axle 21, may extend horizontally through the lug and sustainthe cylinder in a horizontal plane.

In order to center the lug 26 of the cylinder on the rear axle 21, weprovide the latter with spacing sleeves 27 which space the lug centrallybetween the rear ends of the rearlinks.

' ery and one side,

A piston 28 is located-in the cylinder and has a stem 29 which extendsthrou h a stufling-box in the forward head 30 an the forward end of saidstem carries a block 31 which is mounted on the front axle 20.

It will therefore be seen that the cylinder 24 has its rear endsustained on the rear axle 21 while the forward end of the piston-stem29 is attached to the front axle 20 so that when the link-bars 14, 15,16 and 17 are spread out into a substantially horizontal position, as inFig. 3 of the drawings, the piston-stem 29 will be drawn out and thepiston 28 will then be at the forward end of the cylinder.

When the piston has thus been drawn to the forward limit of its strokehowever, the weight of the bed is not placed on the pistonstem, cylinderand cylinder-head because we provide each of the two rear link-bars 16and 17 with rollers or wheels 32, which are of a greater diameter thanthe wheels 20 or 21 and are so mounted as to take the weight of the loadso that said load may be balanced on said larger wheels by a slightpressure on one end or the other of the truck.

By reference, particularly to Figs. 4 and 5 of the drawings, it will benoted that a tie-rod 33, extends horizontally between and connects thetwo rear link-bars 16 and 17, while a similar tie rod 34 extendshorizontally between and connects the two forward link-bars 14 and 15.

It will also be noted that the downturned flange 13 of the angle-bars ofthe bed carries 8. depending plate 35, whose lower ortion is providedwith a slightly elongated perforation 36 through which the tie-rod 34extends so that the bed of the truck is maintained in substantially agiven relative position with respect to forward link-bars 14 and 15, andeven though the bed may be unbalanced by the weight thereon said bedcannot tilt independently of the link-bars 14 and 15.

It will further be noted that the flanges 13 of the angle-bars havebottom-edge notches 37, which, when the links are in their lowermostpositions, will seat around the upper surface of the rear tie-rod 37 andserve as a stop to limit the spreading movement of the links.

The piston 28 controls the movement of the links through the passage ofoil which must pass from one side to the other thereof, and this controlis designed to permit a rapid upward movement of the links and bed butallow only a retarded movement in a downward direction.

The construction for effecting these fast and slow movements will now beexplained, reference being made particularly to Figs. 6 and 7 of thedrawings.

The piston 28 has a rigid center disk 38 with a cup 39 enclosing itaround the peripha disk of flexible material through all of the ontosaid end.

A small vent passage is provided disks and the cup which passage isalways open, and the disks 38 and 41 and the cup are each provided withports 46 which are in register but over which the flexible disk 40seats.

Obviously, when the piston rod 29 is pushed in, as it is when the bed ofthe truck is being raised, it is desired that the movement be rapid andquickly effected, and as this movement takes place, the piston will, ofcourse move to the left and oil will rapidly pass through the largeports 46 and simply unseat the flexible disk 40.

When however, the truck-bed is elevated the piston will be located atthe left end of the cylinder and the bed can be lowered only as fast asthe oil can pass through the small vent passage 45, because the oil willbe compressed against the flexible disk 40 and securely seat it over thelarger ports 46. Therefore the bed will be checked in its descent.

We have found in practice when handling long rolls of paper, and most ofthem are long, that the end of the roll will project be yond the end ofthe bed and it is not convenlent to lift the bed with the roll thereon.We have therefore provided a pivoted handle structure whose innerT-shaped end 47, is

ivotally mounted on the horizontal cross- Ear 18 and this structure hasa tubular bar 48 which extends rearwardly and has a collar with an eye49 therein at its outer free-end. A clip 50 on the end sta -bar 11 ofthe bed will normally hold the tu ular bar.

On the interior of the tubular bar, we provide a telescoping rod 51which may be extended so as to project outwardly beyond the end of thepaper roll 52, when desired.

Another function of the rod 51 and pivoted bar 48 is to assist inturning an up-standing vertical roll of paper over and onto the bed ofthe truck, as will presently be explained.

We also utilize a flexible means in conjunction with the handle tofacilitate the tilting of a paper roll from its vertical to a horizontalposition. This flexible means consists, in this instance, of a chain 53,having a hook 54, at one end thereof for engagement with the eye 49 onthe tubular handle 48,-the chain being attached to a belt or web 55which may extend over the rim-edge of the paper roll, as shown in Figs.1 and 2, without marring or damaging the paper wraps at said edge, andthe other end of the web being attached to a pin or plug 56 which isinserted in the tubular core 57 about which the aper is wrapped'informing the roll.

hen the roll of paper 52 is standing on end as shown in Fig. 1, the sameis tllted slightly to permit the toe 12 of the truck-bed to be insertedthereunder. The pin or-plu 56 is then inserted in the tubular core 57,an the hook 54 on the chain 53 is eng ed with the eye 49, on the end ofthe pivote tubular bar 48.

The telescoping handle-rod 51, having been drawn out of the tube 48, isthen grasped and pulled down, swinging on the crossbar 18, while the bedof the truck remains in an u wardly-inclined position.

As the han le-bar 51 is swung down the paper roll 52 is tilted over, asshown in broken lines in Fig. 1, until it drops against the inclined bedand as the weight of the roll is transferred to the bed the latterbegins to swing down because the weight will s read the lower ends ofthe link-bars apart.

his spreading of the link-bars 14, 15, 16 and 17 can only take place asfast as the oil in the cylinder can flow through restricted passage 45of the piston as the latter and its stem 29 can move in the cylinderbecause the piston-stem 29 has its forward end attached to the shaft oraxle 20 to which the forward ends of the link-bars 14 and 15 are alsoattached.

As the bed settles down to a substantially horizontal position the largewheels 32, will seat on the floor and the flanges 13 of the angle ironsof the bed will rest upon the tie-bar 33.

When the bed has completely settled down, the truck will be supportedmainly by the large wheels 32, and may be readily rocked thereon to lifteither the front or rear end which enables the truck and roll thereon tobe readily turned around end-for-end to move it wherever it is desired.

It has hereinbefore been explained that the bed cannot swingindependently of the forward links 14 and 15 because of the plates 35and their engagement with the tie-rods 34.
